6 planets that could be colonized by humans
The colonization of other worlds has been a long-cherished dream of mankind. Although, today, this dream is still far from being realized. Some even believe it will never turn out to be a chimera. For example, Jean-Jacques Dodin, head of the European Space Agency, said in 2014, "Humanity has no choice but to live on Earth. There is no other place to live. We can't do that on other planets in our solar system, and we can't go to an exoplanet because it's too far away. "
